To @ZZ whom it may concern:

Beit known that 1, ALEXIS LOUIS MANGIN,

a subject of His Majesty the Kingv of Great' Britain, residing at Jeanne dArc, Aylmer East, county of Ottawa, Province of Quebec, Canada, have inventedV certain newand usefullmprovements in Carbureters; and I do hereby declare that thefollowing is a full, clear, and exact description of the invention, such as will enable others skilled'in the art to which it appertains to make and use the sam e.

My invention relates to improvements in carbureters; and the primary object in view is to provide an improved construction wherein provision is made for a current of air circulating in a tortuous course, so that it will absorb or become saturated with -a volatile hydrocarbon, whereby the air becomes im'- pregnated, so as to produce an iniiammable vapor or gas, which maybe economically utilized for lighting, power, and heating` pur,-

poses.

A further object is to expose a large area of the Volatile hydrocarbon in the air-circulation passages of the apparatus, to the end that the air will absorb a maximum quantity of hydrocarbon, and, furthermore, to simplify the construction and to reduce the cost ofV manufacture.

The apparatus which I have devised is intended to sec/ure a' perfect carburization ot'V air within the Very short space of time required for the circulation of an air-current through a machine which is extremely simple and compact, so that said machine will take up very little space and the carbureting operation will be carried 0n continuously.

With these ends in View the invention consists in the novel construction .and arrangement of parts, which will be hereinafter fully described and claimed. s

In the drawings hereto annexed, forming a part of this specication, Figure 1 is a vertical central sectional elevation through a carbureter embodying my invention. Fig. 2 is a sectional plan View thereof taken in the plane of the dotted line 2 2 on Fig. 1.

The same numerals of reference denote like parts in both figures of the drawings.

5 designates a tank, which may be of any suitable form and constructed of any material. This tank is provided with an imper` forate bottom 6, to which is secured a short vertical partition 7, that is arranged close to the wall of the tank, so as to form an intermediate space S, and one portion of this'partition, adjacent to an end of the tank, is perforated, as at 9, to yform anair-ditfusing section, whereby the air can escape from the chamber formed by the partitiononly through 6o the perforations in the diffusing-section 9 and thence Vescape into theV space 8. A circular diifusing-Wall10-is also secured to this bottom 6 of the tank within the chamber of the partition of wall 7, said diusing-wall being provided with a multiplicity of perforations in all portions thereof, as shown by Fig.

1, the circular form and the position of the vwall 10 being indicated *by dotted lines inr `11 designates a false bottom, which is in the form'of an imperforate plate arranged to rest upon the wall or partition Tand the diffusing-wall 10. This false bottom is -parallel to the bottom 6 of the tank, so that it will form a small air-chamber 12 by and between the lbottom 6,'.the false bottom 11, and the perforated wall '10, and this'false bottom ene tirely covers the space'inclosedby the partition or wall 7, so asto form a larger chamber 8o '13, within which last-mentioned chamber is disposed theV diffusing-wall 10. This false bottom joins with the wall of the tank at one end of the latter and along the .two sides thereof; but the opposite end of this false bottom is curved, as shown by Fig..2, and is arranged to extend slightly beyond the perforated section 9 of the wall 7, whereby the projecting edge of the false bottom forms a lip or flange 14, that extends into the space 9o S and overhangs the diffusing perforated sec- -tion 9. I

15 designates the air-inlet pipe, which extends through the top 16 of the .tankthrough the chamber of the tank-andihas its lowerk end united, as at17, in any suitable way to the false bottom 11, whereby saidlair-inletv pipe discharges a current of air directly into the chamber12, which is formed lby the perforated diffusing-wall 10.

1S designates a partition which in plan view is approximately spiral or helical, as shown by Fig. 2, the outer end of said partitioni be- ,ing joined in any suitable way to one side ICO wall of the tank, as at 19 in Fig. 2. From thence said partition extends on spiral or helical lines until it terminates near the airinlet pipe 15. This partition is arranged between the top of the tank and the false bottom 1l, and said partition forms a continuous and substantially helical circulating-passage 20, the same arranged to have communication with the space S of the tank and to discharge the current of carbureted air into a central chamber 21, as will be more readily understood by reference to Fig. 2. The approximately helical partition is supported above the top face ot the false bottom 11 by means of the clips or plates 22, so as to produce the narrow passage 23 between the false bottom 1l and the lower edge of said helical partition. This space 23 allows for the flow of the liquid hydrocarbon beneath the partition, so as to till the lower portion of the tank up to the level indicated by the dotted line X in Fig. 1, which line indicates the liquidlevel wit-hin the carbnreting-tank. The liquid-level is above the lower edge of the helical partition, so as to serve as a seal in preventing the air contained in the spiral circulating-passage from passing beneath the lower edge of' said partition and from one portion to the other of said circulating passage, whereby the air is compelled to follow the tortuous and spiral course which is defined by the formation and provision of the spiral passage within the tank 5.

Any suitable hydrocarbon may be supplied to the apparatus, and as one of the hydrocarbons suitable for use in the carburization of air I may employ gasolene. This liquid may be introduced in any suitable way; but I prefer to employ the feed-pipe 24, the same extending through the top 16 and into the chamber 21. The lower extremity of this pipe is shown by Fig. l as being exteriorly threaded and screwed into a nipple 25 of the footplate 26, the latter serving as the means for supporting the lower extremity of the feedpipe in the plane of the liquid-level which it is desired to establish and maintain in the tank. This foot-plate is shown by the drawings in the form of a clip, by which it may be secured to the false bottom 11 at a suitable point within the chamber 21, and the end portions of this clip-shaped foot-plate are open, so as to allow the free escape of the hydrocarbon when it flows through the pipe 24.

The substantially spiral partition 18 is provided on one face thereof with a fibrous lining 27, and its other face has a similar lining 2 These linings extend from top to bottom of the partition and throughout the length of the same, so that the linings are coextensive with thelineal dimensions of the tortuous air-passage 20. The linings have their lower portions extended below the level indicated by the line X, so as to be immersed in the hydrocarbon, whereby the linings may be saturated with the hydrocarbon and a large area of hydrocarbon in thin film or strata is exposed eeaees to the air as it circulates and travels through the spiral passage within the apparatus. Below the top 16 of the tank is arranged a metallic plate 29, which is provided on its under surface with a fibrous layer 30, the latter having engagement with the end edges of the linings 27 28 within the spiral circulating-passage, whereby said linings will conduct the hydrocarbon to the top layer 30, thereby augmenting the area of saturatable fiber which is exposed to the contact of the air as it circulates within the apparatus. The necessary close contact of the top lining or layer 30 with the vertical linings of the helical partition is obtained by pressing the top plate 29 downwardly in a positive manner, owing to the employment of compression devices that are adapted to also fasten the top16 to the tank. As shown by Fig. 1, a screw-bolt 31 is arranged to pass through lugs 32 33, which are provided on the tank and the top, respectively, and this bolt is provided with a clamping-nut 34, that is arranged to bind upon the lug 33 and to draw the top 16 toward the tank, thereby firmly and detachably securing the top to the tank and incidentally compressing the top fibrous layer 30 between the plate 29 and the iibrous linings applied to the helical partition. I would have it understood, however, that the top 16 may be secured in place by any other means within the skill of the constructor.

A pipe 35 is secured to the top 16 of the tank in a position to communicate with the chamber 2l, and this pipe is adapted to serve as the means for conducting the charged vapor or carbureted air from my improved apparatus to any place where it may be desired to store the vapor for service or to utilize the same in burners of any character. A fibrous lining 36 is also provided within the tan k, the same extending the full height of the tank, so that its lower portion is immersed in the hydrocarbon, the remaining area of the lining 36 being exposed to the air circulating in the tank.

In operation the air is forced by any suitable means through the pipe 15 into the chamber 12, which is formed by the perforated diffusing-wall 10, and the airin escaping through this chamber is compelled to pass through the minute perforations of said wall, whereby the air is mechanically broken upin order to better expose it to saturation by the vapor of the hydrocarbon. This diusion of the air by passing it through the wall lO is repeated as it makes its escape from the chamber 13 by passing the air through the perforations in the diffusing-section 9 of the wall or partition 7, from whence the air passes into the space S and thence into the passage 20, through which it is compelled to circulatein a spiral course (represented by Fig. 2) until itis finally discharged into the chamber 21, from which chamber the carbureted vapor is conducted by the pipe 35 to the place of storage or utili- Zation.

By reference to Fig. 1 it will be noted that IIO perforated section 9 of the Wall 7 at one endY y of the chamber 13, and that the air' in traversing the passage 20 is compelled to have contact mechanically with' the saturated lin' ings 27, 28, 30, and 36, whereby the operation of charging or impregnating the air with hy-v drocarbon vapor may be carried to an exceedingly high degree of efficiency and result in the production of a charged vapor containing a maximum percentage of the hydrocarbon.

Changes within the scope of the appended claims may be made in the'form and proportion of some of the parts While their essential featuresare retained and the spirit of the invention is embodied. Hence I do not desire to be limited tothe precise form of all the parts as shown, reserving the right to vary therefrom. i

Having thus described my invention, what Iclaim as new is- Y l. A carbureter comprising a tank provided with afalse bottom `terminating at one end Within the tank to forman opening or passage, .a partition having a perforated diffusing-section at-the end of the false bottom and secured to thefalse bottom and the bottom of the tank, aradially-.perforated dius-v ing-Wall situatedwholly within'the chamber formed by the first-named partition, a suitable oil-inlet to said chamber, an air-pipe discharging into the chamber produced by said diffusing-Wall, a tortuous circulatingpassage within the tank, and a carburetedair outlet communicating'with said passage, substantially as described.v

2. A carbureter comprising a tank having means for diffusing air below the level of a hydrocarbon-bath, a helical partition Within said tank and forming therein agcorrespondf ing circulation-passage and a central cham-- ber, the linings Within the tank and on the helical partition, a top clamped to the tank, a top layer interposed between the linings of the partitions and the clamped top, and an outlet-pipe communicating with the central chamber, substantially as described.

3. A carbu'reter comprising `a tank provided with a false bottom, a helical partition secured within the tank and'to the false bottom thereof and forming the 'liquid-circula'- tion space at the lower edge of said partition, a foot-plate secured to the partition, a feedpipe supportedv by the foot-plate at the desired elevation, means for diffusing air below the false bottom and in the hydrocarbonbath, and a carbureted-airv outlet communieating with the liquid-circulationspace, substantially as described.

In witness whereof I have hereunto set my hand in the presence of two witnesses.
